function Beeper(frequency, [fVolume], [durationSec]);
Play a beep sound. Default is 400 Hz for .15 sec.
frequency can be a number, or else the string ‘high’, ‘med’, or ‘low’.
fVolume - normalized to range of 0 - 1. Default is 0.4;
Warning: 1 is the maximum volume and is often very loud!
Funny name is because Matlab 6 contains a built-in function called “beep”.

- Added fVolume param
- Swapped parameter order

- Scaled down the volume of the sound to match the system volume better. It was at maximum volume.
Would scare you enough to rip the bite bar off it’s mount!
And switched to useing the sound() function, instead of the soundsc() function
which, by default, maximizes the volume.
- Update, using the PsychToolbox Snd function which should return immediately.
Were experiencing delays with sound function
